CAMERA.

Application filed August 4, 1922. Serial No. 579,555.

To all whom t may concern.'

Be it known that I, GUNNAR Quin-moisi, a subject of the King of Sweden, residing in tie city or New Rochelle, county of Vestchester, and State ot New York, have Iinvented certain new and useful improvements in Cameras, of which the following is a speciiication, reference being had to the accompanying drawings, forming a part hereof.

This invention has for its object to provide improved means whereby, in a photographic camera, either the whole or one part or another part of the sensitized surface, whether of iilm or plate, can be exposed when the shutter is open, so that the photographer may make a negative which shall cover the whole ot the plate or film, or maj.' make two negatives, in succession, upon one portion and another portion of the same film. Not only can economy in the use oli' the plate or lilm be practiced thereby, but it is possible to make upon one film or plate, side by side, negatives of two different objects or of the same object as seen from different points of view. In accordance with the invention a secondary movable shutter or mask is arranged in operative yrelation vwith respect to the sensitized surface and operating and guiding means are provided therefor so that such shutter or mask may stand in close proximity to one part or the other part of the sensitized surface, so as to exclude light therefrom, leaving the other part to be exposed when the primary shutter is open, or may be moved out of the path of light between the lens and the sensitized surface so that the whole of such surface shall be exposed when the primary shutter is open.

The invention will be explained more fully hereinafter with reference to the accompanying drawings in which it is illustrated, and in which- Figure l is a top view, partly in horizontal section, of a box camera, otherwise of ordinary construction, equipped with the present improvement.

Figure 2 is a view of the same partly in side elevation and partly in vertical section.

Fi ures 3 and 4 are partial views, similar to Flgure 2, illustrating different positions of the shutter actuating mechanism.

Figure 5 is a partial view in horizontal section, on the plane indicated by the broken line 5-5 of Figure 3.

The improvement. is illustrated in the drawings as applied to a box camera of ordinary construction and adapted for a film, having a box-like casing a, film spools l) and Zi', and guides a and a2 for the lm as it passes Jr'rom one spool to the other. The position or the usual object lens is indicated by broken lines at c in Figures l and a, 'the position of the usual primary shutter being indicated by its operating means at CZ. Pivoted at c, at one corner of the casing c, is a rectangular U-shaped or threesided guide iframe, the side members e ot which are grooved to support and guide in its movements the secondary shutter f, the purpose of which is to mask one part or another or" the sensitized surface of the film or plate. The guide frame e, c swings ilreely upon its pivot and the secondary shutter or mask f slides :treelv in the guide 'frame under the influence or the operating mechamsm to be described. Normally the frame and the mask or secondary shutter stand in the position shown in Figure 2, so that the entire sensitized surfacekoi: the film or plate, at the rear ot the camera box, is exposed when the primary shutter is open. T he first movement oi" the operating mechamsm swings the trame e, c to the position shown in Figure 3, when the secondary shutter or mask f stands close to the sensitized surface and protects the same from exposure when the pri,V iary shutter is opened, so that the negative is Y[formed only on the other part of the sensitized surface. A further movement ot the operating means causes the secondary shutter or mask f to slide in the guide trame e, e from the position shown in Figure 3 to the position shown in Figure fr, in which position it masks the other or left hand portion of the sensitized surface. leaving the right hand portion exposed, @n the inner or under side of the mask f is formed an eye f which is engaged by a rod g. The latter is carried by a substantially right angled arm g', the member g2 ot which is slotted longitudinally as shown at g3, in full lines in Figure 5 and in broken lines in Figures 2, V3 and 4, to engage the spindle 72. of the operating cam 7L. The latter is formed with an actuating cam slot 7b2 to engage a pin g* fixed in the arm g2. For convenience in manufacture the hub 72.3 of the actuating cam is 'formed with holes zf1 for engagement with corresponding pins z' of a head i secured to an operating` spindle 2 which is mounted in a casing 3 secured to the casing a of the camera, a sgi-nig` i* serving to hold the head in engagement with the huh la of the actuatingcem, but permittingl disengagement when the inner easing` e is to he removed, with the parts carried thereby, from the outer casing a.

Fixed to the inner casing en, and suitahl),T spaced therefrom is a cam plate 7u termed with a ,oc/enerall)7 lll-shaped t in slot Zr, with which is engaged the pin f/t carried by the arm (/2 ant haring' its other end engineer in the cam slot 72,2 ot `the actuating cam 7a.

The operating spindle 2 is pro\.f'ided 'with lle and with a pointer GJ. n the narts are in the osition shown in Figure i2, Vwith the pointer tejuide 'traine e, e nids elette t the inner casi (1,, with the mask ji shown in s ligure. TWith the mow` ot' the ogerat"ne` spindle to the position indi cated in Fipure E, with the pointer at Uhr the arm ,"2 is euused firstto slide inwarfil, then swung upon the spindle 7iy a.' en axis, and is then caused to slide outward :1nd at the same time 'to he swunjf slight nnen the same wherehy the guide c, e is swung;` 'from the position shown in Figi'- ure 2 to the position showrure 3 with the mash masking; the ht hand side ol' the sensitized surface et the liiin or plate, `he left hand part et the surtaee heine at the same tim, exnosedirhen the primary shutter at d is onened. .n'this movement the pin ,f/t guided the first two portions oit the slot 72 et the fixed or guiding eem Il nonY the nnwementet operating handle he Continued until the pointer 1.1i reaches the point marked right the morement ot the arm tv/2 hy the actuating rem continued, the piu ,f/'i' being' guided in the third 'portion oi the cam ,atreve Zi', so that the i'nask ,t is drawn in the Afluide 'frame 6, e iti-om the position shown .in Figure 3 to the position shown in Figure el, therebyv masking the lett hand portion ot the sensitized surface and leaving` the right hand portion exposed. lhen the movement ot the operatingr spindle is reversed, the mask will he moved 'from the position shown in Figure e lirst to the position shown in Figure 3 and then to the position shown in Figure 2.
